Calendar & Todos
Sickle is a daily planning app that brings your calendar and todos into one unhurried space — so you can see clearly, decide quietly, and work with intention.
Agenda
Tasks
"Everything important stays in view — the day's shape, your tasks, what's next."— Built for daily planning
Three things that make Sickle different from every other daily planning app: your calendar and todos stay close, so you can see what is next.
See the shape of the day before deciding where tasks belong. Time is the constraint, so you can plan your day around it.
Add tasks quickly and keep the list close to your working context. No extra apps, no separate tabs.
Separate open work from completed work without digging through views. The important stuff surfaces.
